According to a blog post from Messaging app WhatsApp, the company is now getting over one billion messages sent using its platform a day.

That’s a lot. My wife uses this app to communicate with her cousin while she is studying abroad and said that she likes it for the purpose it serves.

I have to think though, despite the cross platform nature of the app, that iMessage will essentially dominate this market. I can’t imagine that a year from now, text message replacement apps, will have substantial enough use.
